Louisa K. Fast 1920s Letter from Bess Armstrong Hawes
No full textA letter to Louisa K. Fast from Bess Armstrong Hawes (Mrs. MC. Armstrong). It is not dated. Louisa K. Fast was a prominent member in the Women's Suffrage Association, which later became the League of Women Voters in 1920. She was employed by the LWV to speak throughout Ohio to encourage women to form local chapters of the group. Later, Miss Fast was employed in the New York office of the International Relations Branch of the LWV. The collection of Louisa K. Fast correspondence are related to the League of Women Voters. This letter is from a private collection and was loaned to the library by Bonnie Boroff. The letter's contents are as follows.
Dear Miss Fast:
I wish I could stow myself away in your present and go with you.
If I could look back over the last few years & feel that I had done half as much for anything as worthwhile as The League of Women Voters & the C & CJ war it would be a very satisfactory feeling.
You might be interested to know that when the couple who owned the guppies took them home they made the fresh water too cold & all died (I had no report on the turtle).
Thank you for your card. Of course you were too busy to see me & I was in bed or just off it with jaundice & couldn't get to any meetings.
Bon Voyage,
Bess Armstrong Hawes

K-theory for group C*-algebras
No full textThese notes are based on a lecture course given by the first author in the Sedano Winter School on K-theory held in Sedano, Spain, on January 22-27th of 2007. They aim at introducing K-theory of C*-algebras, equivariant K-homology and KK-theory in the context of the Baum-Connes conjectur
Search for eta(c) decays into pi pi and K(K)over-bar
No full textUsing 58 million J/psi) events taken with the BESII detector, a search for eta(c) CP violating decays into pi pi and K (K) over bar has been performed. No clear 77, signal is observed, and upper limits for B(eta(c) -> pi pi) and B(eta(c) -> K (K) over bar) are given at the 90% confidence level, B(J/psi -> gamma eta(c)) center dot B(eta(c) -> pi(+)pi(-)) < 1.1 x 10(-5), B(J/psi -> gamma eta(c)) center dot B(eta(c) -> pi(0)pi(0)) < 0.71 x 10(-5), B(J/psi -> gamma(eta c)) center dot B(eta(c) -> K+K-) < 0.96 x 10(-5), and B(J/psi -> gamma eta(c)) center dot B(eta(c) (KSKS0)-K-0) < 0.53 x 10(-5).Physics, Particles & FieldsSCI(E)1ARTICLE2337-3414
Measurement of the ratio of branching fractions B(B0→K∗0γ )/B(B0s→φγ ) and the directCP asymmetry inB 0→K∗0γ
No full textThe ratio of branching fractions of the radiative B decays B0→K⁎0γ and B0s→ϕγ has been measured using an integrated luminosity of 1.0 fb−1 of pp collision data collected by the LHCb experiment at a centre-of-mass energy of s√=7TeV. The value obtained is
B(B0→K⁎0γ)B(B0s→ϕγ)=1.23±0.06(stat.)±0.04(syst.)±0.10(fs/fd),
where the first uncertainty is statistical, the second is the experimental systematic uncertainty and the third is associated with the ratio of fragmentation fractions fs/fd. Using the world average value for B(B0→K⁎0γ), the branching fraction B(B0s→ϕγ) is measured to be (3.5±0.4)×10−5.
The direct CP asymmetry in B0→K⁎0γ decays has also been measured with the same data and found to be
ACP(B0→K⁎0γ)=(0.8±1.7(stat.)±0.9(syst.))%.
Both measurements are the most precise to date and are in agreement with the previous experimental results and theoretical expectations
